It seems to me that the decision theory generally favors acting as if one has rare talent and circumstances, as opposed to the alternative, more likely hypothesis, which is probably the contrarian hypothesis of being a simulation in any event. Attempts to justify common sense, treated honestly, generally end up as justifications of novel contrarian hypotheses instead.

Also, one who tries to conform to official norms rather than to ubiquitous surrounding behavioral patterns will rapidly find oneself under attack, nominally for violating official norms. I think that the way to go is usually to conform but also to recognize that the standards to which one is conforming do not correspond to explicit beliefs at all, or even to implicit decision theories.

Treat social reality as a liquid in which one swims, not an intellectual authority, but don't attack a liquid without some very heavy ammo, and generally don't attack it even if one has such ammo, it's not an enemy, an agent, or a person.
